- set min height for grid only in edit page,
so it won't show a lot of empty space for pages
with few blocks
- make the journal block resize when expanding
content
- [FOR TESTING!!] resize the block everytime
a collapsible is expanded or collapsed
inside the block. Need to check what happens
to the layout structure of the blocks that
are under the block that resizes.
